Well, I'm fairly sure that the age requirements are a way of judging an applicants grammar (in relation to age) as well as a way of judging suitability to the forum, for example: a 12 year old would not be suitable for Mature Disscussions. The gender, I'm really not sure about, but I would guess it just there so we can know whether to refer to the applicant as he or she as the username may not really indicate which is appropriate.

To become a super moderator, you must be chosen by the admins, and have a long standing good reputation as a forum or section moderator first. In other words, it's the old "don't call us, we'll call you."

DrFred nailed it perfectly, I couldn't have said it better myself. Age is to determine our expectations on what the user will be like. We don't want to have a 23 year old moderator who posts like a 10 year old and we don't want to have too many 10 year old moderators (members in the younger age range are abundant on here).

Sex is just a statistical reference, as MikePavy pointed out it is more like a "filler". We ask it in order to get a better feel for our "could be" co-mods. After all, we don't know who you are and its necessary to get down some basic information (because the last thing we want is for a mod to refer to his/her co-mod as a she when it's really a he ). Keep in mind that as Jeevan pointed out, one's sex is never used as a determining factor in the selection process. If you are offended by the question you can choose to omit your sex (but not your age).

This post has pretty much regurgitated the great words of my predecessors, but I felt the need to reiterate what's been said for the sake of further clarification. Feel free to PM me if you have further concerns regarding this matter.
